How to Use Gross Margin Calculator
The Gross Margin Calculator offers three calculation modes to cover the most common business finance scenarios:
- Revenue & Cost → Margin — Enter sales revenue and cost of goods sold (COGS). The Gross Margin Calculator instantly shows gross profit, gross margin %, and cost ratio.
- Revenue + Target Margin → Max Cost — Enter your expected revenue and a target gross margin percentage. The Gross Margin Calculator returns the maximum COGS you can afford while hitting your margin goal.
- Cost + Target Margin → Suggested Price — Enter COGS and a target gross margin. The Gross Margin Calculator derives the selling price required to achieve that margin.
Switch between modes using the toggle at the top of the tool. All results update in real time as you type.
Formula & Theory — Gross Margin Calculator
The Gross Margin Calculator is built on three core formulas:
Gross Profit = Revenue − COGS
Gross Margin = (Gross Profit ÷ Revenue) × 100 [%]
Cost Ratio = (COGS ÷ Revenue) × 100 [%]
For reverse calculations, the same relationship is rearranged:
Max COGS = Revenue × (1 − Target Margin ÷ 100)
Suggested Price = COGS ÷ (1 − Target Margin ÷ 100)
| Symbol | Meaning |
|---|---|
| Revenue | Total sales receipts before any deductions |
| COGS | Direct costs of producing the goods or services |
| Gross Profit | Revenue minus COGS |
| Gross Margin | Gross profit as a percentage of revenue |
| Cost Ratio | COGS as a percentage of revenue (100 − Margin) |
Why Gross Margin Matters
Gross margin reveals how efficiently a business converts revenue into profit before overhead. A rising gross margin — tracked with a Gross Margin Calculator over time — signals improving pricing power or falling production costs.
